CHAIR-SEATING NEEDLE.

SPECFICATION forming part of Letters Patent No. 278,982, dated June 5, 1883,"

Application filed June 29, 1882. (No model.)

-To all whom, t may concern .Be it known that I, CHARLEs R. Lone, of Louisville, in the county of Jefferson and State of Kentucky, have invented a new anduseful Improvement in Chair-Seating Needles, of

iwhich the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar letters of reference indica-te corresponding parts in all theiigures.

Figure l is a plan view of a portion of 'a chair-seat.v Fig. 2 is a sectional elevation of aportion of my needle, showing part of a chaii` frame. Fig. 3 is a side elevation of a portion thereof turned one-quarter of a revolution. Fig. 4 is side elevation of the same turned through the second quarter of a revolution. Fig. 5 is a side elevation ot' the same turned through the third quarter of a revolution. Fig. 6 is a sectional end elevation of the nee-- dle shown in the first position, and illustrating its use. Fig. 7 shows au elevation of the needle and a section of port-ions of a chairframe.

The object of this invention is to facilitate the seating of chairs with a plaiting of cane or other material.

The invention consists in a chair-seating needle constructed with a body having four (more or less) rows of alternating spaces and notches with end journals, either or both of which are provided witha screw-collar and with a handle, as will be hereinafter fully described, whereby a uniform diagonal plaiting will be formed, as will be hereinafter i'ul ly described.

In making my chair-seating needle I take a rod of iron or other suitable material of' convenient size and turn down its end parts, A, to about one-third the diameter of the said rod, leaving the body E ot' the needle of such a length 'as to fit in between the front and rear bars of the seat-frame of the chair to be seated, while its end parts or journals, A, rest upon the said bars. Screw-threads are cut upon the outer ends of one or both the parts A, to receive a collar or collars, B, to be screwed up against the front and rear bars, C, of the seat` frame, or against either oi' them, to prevent the needle from having any longitudinal movement while in use.

For convenience in turning the needle it is provided with a handle, D, on each or either end.

In forming the body E of the needle, beginning with the needle in the position shown in Fig. 2, a rabbet or notch the width of the warp to be used and-of a depth equal to about onethird the diameter of the said body is formed in one end. A space of the width of two Warpstrands is then left, and a notch or cross-slot the width of two warp-strands is cut in the upper side of the said body, and so on to the other end of the said body, the alternating notches and spaces being oi' uniform width and depth. The needle is then turned one-quarter of arevolution, and another series of alternate spaces and notches are formed, each equal in width to the width of two warp-strands, and beginning with a space, as in Fig. 3. The needle is then turned through the second quarter of a revolution, and another series of alternate spaces and notches are formed, beginning in this case with a space equal to the width of the warp to be used-that is, ofthe same width as the rabbet iirst made-and then continuing with a' notch and space alternately, each the width of two warp-strands, as in Fig. 4. The needle is then turned through the third quarter of a revolution, and another series of alter-v nate notches and spaces are formed, each the width of two warp-strands, and beginning with a notch or rabbet, as in Fig. The needle is then turned through the fourth quarter of a revolution, which brings it back to the firstposition, as in Fig. 2. Vith this construction a diagonal pl ait-ing will be formed, each strand passing over two strands and under two strands alternately, as hereinafter described.

Vhen making double-bottomed seats, the warp or first way 7 is wound around the side bars of the seat-frame by hand, in the ordinaryV manner. A needle is then passed beneath the warp of the upper part o1 the seat, and another needle is passed above the warp of the lower part of the seat, the parts A of the needles being held against the front and rear bars of the seat-frame by the said AB up against the said front and rear bars of the seat-frame. The upper needle being' ar- IOO ranged beneath the warp or first way. oi' the v the woot` or second way77 is passedand is then pushed to the other side ofthe seat-frame. The needle is then turned through one-quarter of a revolution, so as to raise other strands, and another Woof-strand is passed through, and so on until the woof extends to or nearly to the needle, which is then removed, and the remaining space is afterward iilled out by hand in the ordinary manner. In this way a uniform diagonal plaiting will be formed, each strand of woof passing over two strands of warp and under two1 strands alternately. rPhe operation of the under needle upon the strands of. theunder portion ofthe seat is substantially identical, the strands. of the latter being depressed by such needle instead of elevated, as in the case of the upper needle. The elevated or raised parts Aon the body portion of the need le are arranged in helical order, or like the thread' ofa screw. Such raised portions support the warp-strands in pairs, which are lifted or raised' above the alternating pairs of warpstrands, the latter resting in the hollows be tween the raised portions. Vhen the needle is revolved, it is thus eaused to drop one strand of each raised pair and take up a strand on the opposite side of the remaining raised strand at each quarter-revolution. A different needl'e is required for each different width of warp-strands, the raised portions and the notches in each case being the width of two strands, except at each end of the needle, where they run ont to the width of one strand, as stated. Should it be desired to change the pattern ofthe fabric, the depressions and raised portions ofthe needle maybe made of widths corresponding to the width of the alternating numbers of strands. Vhen the chairs and their top rounds are all of 011e width, the collar or collars B do not require to be adjusted,

and they may be integral with the needle.

Having thus described my invention, I claim as new and desire to secure by Letters Paten-tl. A chair-seating needle constructed substantially as herein shown and described, and consisting of the body E, having four (more or less) rows of alternating spaces and notches, journal A, provided with screw-collar B, and handle D, as set forth.

2. A chair-seating needle consisting of the body E, having four (more or less) rows of alternating spaces and notches, the journals A, and handle D, substantially as specified.
